Abstract

A wide research program provided by ultra-relativistic heavy ion collisions is ongoing at the Large Hadron Collider with the aim of studying the properties of QCD matter at extreme temperatures and densities. Jets produced in such conditions contribute to the understanding of the mechanisms responsible for the hard scattered partons energy loss while crossing the hot and dense medium. The large acceptance and high granularity of the ATLAS Detector is well suited to pursue these studies, namely the dependence of jet suppression on the jet transverse momentum and cone size, as well as the internal structure modification. Measurements of these observables provided by the Pb+Pb collision data collected during the 2010 and 2011 LHC runs, at the nucleon-nucleon center of mass energy of 2.76 TeV, are presented.
